this one helps. It seems that you are following the wrong approach
let us assume we have a class called users like following
code :
public class User: IValidatableObject
     public int Id{get; set;}
     public string UserName{get; set;}
     public IEnumerable<ValidationResult> Validate(ValidationContext validationContext)
               yield return new ValidationResult("Username field is required!", new string[]{"UserName"});
               // check if another User has the same username already
               var db= new YourDbContext();
               var exists=db.Users.FirstOrDefault(t=>t.Id!=Id && t.UserName.ToLower()=UserName.ToLower());
                   yield return new ValidationResult("Username is already used by another user!", new string[]{"UserName"});

hop of those help? (sorry for my bad english) I would recomend that you do not use the grid event to validate your data - do this on your POCO properties setter - its cleaner, easier to mantain and if you use this POCO with another control your validation will still work.
Since you need to access a service to validate the value, your best bet is to implement the interface INotifyDataErrorInfo, that allows you to make asynchronous validation, look here: http://weblogs.asp.net/fredriknormen/archive/2009/11/22/silverlight-4-and-asynchronous-validation-with-inotifydataerrorinfo.aspx and here http://www.silverlight.net/learn/data-networking/validation/asynchronous-data-validation

around this issue You can validate the form fields in the beforeSubmit function. In this function you can validate the fields and add the highlight class to the element you want. You can do something like this:
code :
beforeSubmit: function(postdata, formid){ 
       //more validations
       if ($('#exec').val()==""){
                return [false,'ERROR MESSAGE']; //error
      return [true,'']; // no error

like below fixes the issue I want to validate a field called survey_id which is an input from user for uniqueness. It is working properly and giving the correct response when adding the new record, but when I tried to edit this record it is giving an error [unique] => Provided value already exist. So what I want is to exclude the survey_id of the current record from uniqueness check and if user input some other value for survey_id it should check for uniqueness search. , It will work with this validation rule
code :
        ->requirePresence('survey_id', __('msg_required'))
        ->notEmpty('survey_id', __('msg_required'))
        ->maxlength('survey_id', 32, __('msg_maxlength'))
        ->alphaNumeric('survey_id', __('msg_surveyid_format'))
        ->add('survey_id', 'custom', [
            'rule' => function ($value, $context) {
              if (!empty($context['data']['projectId'])) { $values = array($context['data']['projectId']); } else { $values = array(); }
              $data = $this->getSurveyId($value, $values);
              return (!empty($data)) ? false : true;
              'message' => __('msg_surveyid_exsist')]);

        return $validator;

public function getSurveyId($surveyId = null, $exclude = null) {

        $where = array('p.survey_id' => $surveyId);
        if (!empty($exclude) && is_array($exclude)) {
          $where[] = array('p.id NOT IN' => $exclude);
        return $this->db->newQuery()
                        ->from(['p' => 'projects'])

I wish did fix the issue. For the validations to work for the columns using Editor Templates you need to add the following in your Editor Templates
code :
    (Html.AthenaTransportDdl("GetPricingPolicyTypes", "Enterprise", HttpVerbs.Post)
.OptionLabel(Html.GetResource(AthenaWeb.Models.Common.XmlResourceNames.CommonXml, "PricingPolicyTypeOptionLabel"))
